摘　　要：城镇化和资源环境承载力耦合的时空演化是生态、地理、经济社会学等研究的重要内容之一,对促进城镇的可持续发展具有重要意义。为研究县域尺度上河西走廊城镇化与资源环境承载力协调度的空间分布格局,基于核密度分析、探索性分析、时空数据模型等方法,对该区域城镇化和资源环境承载力协调度的空间异质性及其动态演进过程进行了研究。结果表明:2000-2018年,河西走廊城镇化与资源环境承载力的协调度呈先递减后升高趋势,协调度峰值在0.35~0.42,现阶段仍以不协调为主;区域城镇化与资源环境承载力协调度的空间分布不均衡,西北高东南低,存在空间集聚和空间自相关现象,热点主要分布在酒泉-嘉峪关等传统工业区,冷点主要分布在东南部的武威区域;区域城镇化与资源环境承载力协调度主要受环保治理投入、产业结构和开发效率等因素的影响。河西走廊城镇化与资源环境承载力协调发展格局及其演化机制的研究对促进该地区城镇化与生态环境协调发展、实现丝绸之路经济带城镇可持续发展具有重要意义。The spatiotemporal evolution of the coordinated development of urbanization and resource-environment carrying capacity is one of the most important topics in ecology,geography,economic sociology. It is of great significance for promoting the sustainable development of cities and towns. To clarify the spatial distribution of the coordination of urbanization and resource-environment carrying capacity in Hexi Corridor at the county scale,the spatial heterogeneity and dynamic evolution of the coordination level of urbanization and resource-environment carrying capacity in this region were examined by nuclear density analysis,exploratory analysis,and spatiotemporal data model. The results showed that: From 2000 to 2018,the peak values of coordination degree between urbanization and resource-environment carrying capacity of Hexi Corridor ranged from 0.35 to 0.42,showing a trend of first decreasing and then increasing,and mainly uncoordinating at the present stage. The spatial distribution of coordination level of regional urbanization and resource-environment carrying capacity was unbalanced,with the northwest being higher than the southeast,and with spatial agglomeration and spatial autocorrelation. The hotspots were mainly distributed in Jiuquan,Jiayuguan and other traditional industrial areas,whereas the cold spots were mainly distributed in Wuwei in the southeast. The coordination level of regional urbanization and resource-environment carrying capacity was mainly affected by environmental protection investment,industrial structure,and development efficiency. Our findings are of great significance for promoting the coordinating development of urbanization and ecological environment in Hexi Corridor and for achieving the sustainable development of cities and towns along the Silk Road Economic Belt.
